The boranediylation of dihydroxy compounds and exchange reactions involving R-B-O groups of a number of their O-boranediyl derivatives with ¹⁸O and ¹⁰B labelled triethylboroxines has been investigated. It has been found that in simple 1,2-dihydroxy compounds only the RB group is substituted or exchanged. In hydroxy compounds such as ninhydrin 7 and octahydroxy- cyclobutane 6 both RB and RBO groups are involved. The mechanisms of these exchange reactions arc discussed.
